In OS X 10.4.6 *csh are hard links:

 > ls -li *csh
3441155 -r-xr-xr-x   2 root  wheel  347016 Aug 22  2005 csh
3441155 -r-xr-xr-x   2 root  wheel  347016 Aug 22  2005 tcsh

on the other hand sh and bash are not:

 > ls -li bash sh
3441151 -rwxr-xr-x   1 root  wheel  581636 Aug 22  2005 bash
3441179 -r-xr-xr-x     1 root  wheel  581636 Aug 22  2005 sh

Curious indeed.
